A construction comprising:

• a framework comprising a plurality of first framework members provided at predetermined intervals and a plurality of second framework members configured to couple the first framework members that are next to each other;
• and
• a plurality of panels held by the framework,
• wherein one or more of the panels are configured to be capable of transmitting visible light,
• wherein one or more of the panels configured to be capable of transmitting visible light each are a lighting device,
• wherein the lighting device includes
• a light source, and
• a light guide configured to be capable of transmitting the visible light and includes a light guide plate configured to guide light emitted from the light source, and
• wherein the light guide plate includes
• a light incident surface facing the light source and into which the light emitted from the light source enters,
• a first principal surface provided on an interior of the construction and from which the light guided in the light guide plate exits, and
• a second principal surface provided on an exterior of the construction and opposing the first principal surface,
• wherein the light guide includes a light extractor configured to allow the light guided in the light guide plate to exit from the first principal surface,
• wherein the first principal surface and the second principal surface at both the upper and lower ends of the light guide are respectively held by a pair of holding members provided on the inner surfaces of the corresponding first framework members, and
• wherein the light guide plate is sandwiched near the ends of its upper and lower surfaces by the second framework members through each pair of the holding members.
